Get ready for a facepalm: 90% of credit card readers currently use the same password.
The passcode, set by default on credit card machines since 1990, is easily found with a quick Google searach and has been exposed for so long there's no sense in trying to hide it. It's either 166816 or Z66816, depending on the machine. Snipper tool.
With that, an attacker can gain complete control of a store's credit card readers, potentially allowing them to hack into the machines and steal customers' payment data (think the Target(TGT) and Home Depot(HD)hacks all over again). No wonder big retailers keep losing your credit card data to hackers. Security is a joke.
This latest discovery comes from researchers at Trustwave, a cybersecurity firm.
Administrative access can be used to infect machines with malware that steals credit card data, explained Trustwave executive Charles Henderson. He detailed his findings at last week's RSA cybersecurity conference in San Francisco at a presentation called 'That Point of Sale is a PoS.'

The problem stems from a game of hot potato. Device makers sell machines to special distributors. These vendors sell them to retailers. But no one thinks it's their job to update the master code, Henderson told CNNMoney.
'No one is changing the password when they set this up for the first time; everybody thinks the security of their point-of-sale is someone else's responsibility,' Henderson said. 'We're making it pretty easy for criminals.'
Trustwave examined the credit card terminals at more than 120 retailers nationwide. That includes major clothing and electronics stores, as well as local retail chains. No specific retailers were named.
The vast majority of machines were made by Verifone(PAY). But the same issue is present for all major terminal makers, Trustwave said.
A spokesman for Verifone said that a password alone isn't enough to infect machines with malware. The company said, until now, it 'has not witnessed any attacks on the security of its terminals based on default passwords.'
Just in case, though, Verifone said retailers are 'strongly advised to change the default password.' And nowadays, new Verifone devices come with a password that expires.
In any case, the fault lies with retailers and their special vendors. It's like home Wi-Fi. If you buy a home Wi-Fi router, it's up to you to change the default passcode. Retailers should be securing their own machines. And machine resellers should be helping them do it.
Trustwave, which helps protect retailers from hackers, said that keeping credit card machines safe is low on a store's list of priorities.
'Companies spend more money choosing the color of the point-of-sale than securing it,' Henderson said.

This problem reinforces the conclusion made in a recent Verizon cybersecurity report: that retailers get hacked because they're lazy.
The default password thing is a serious issue. Retail computer networks get exposed to computer viruses all the time. Consider one case Henderson investigated recently. A nasty keystroke-logging spy software ended up on the computer a store uses to process credit card transactions. It turns out employees had rigged it to play a pirated version of Guitar Hero, and accidentally downloaded the malware.
'It shows you the level of access that a lot of people have to the point-of-sale environment,' he said. 'Frankly, it's not as locked down as it should be.'
The hacking spree targeting underground marketplaces has claimed another victim as a database from card shop Swarmshop emerged on another forum.
By the looks of it, the leak contains the records of the entire Swarmshop community along with all the stolen card data traded on the forum.
Full data dump
Details about the hack remain unknown but the leak exposes 12,344 records with nicknames, hashed passwords, contact details, activity history of Swarmshop administrators, sellers, and buyers.
Researchers at cybersecurity company Group-IB discovered that the leak occurred on March 17, a day before Carding Mafia suffered a breach that exposed email addresses of close to 300,000 members.
According to Group-IB, the Swarmshop dump includes details from 623,036 payment cards issued by banks in the U.S., Canada, U.K., China, Singapore, France, Brazil, Saudi Arabia, and Mexico.
The researchers also found “498 sets of online banking account credentials and 69,592 sets of US Social Security Numbers and Canadian Social Insurance Numbers.”
Whoever breached Swarmshop did not give any information about the hack and just dropped a message with a link to the database.
Initially, the card shop administrators argued that the data was from a previous breach in January 2020, when a hacker tried to sell the forum’s user database. Members were asked to change their passwords, though.
Group-IB analyzed the latest dump and determined that it was new, based on the most recent user activity timestamps.
“In total, the databased revealed the records of 4 cardshop admins, 90 sellers, and 12,250 buyers of stolen data, including their nicknames, hashed passwords, account balance, and contact details for some entries” - Group-IB
Swarmshop is a relatively new carding forum operating since at least April 2019. By March 2021, it attracted more than 12,000 users and had data from over 600,000 payment cards on sale.
Not an isolated incident
March seems to have been a bad month for underground forums, Swarmshop being the third one hacked in this timeframe.
At the beginning of the month, BleepingComputer reported that Maza (or Mazafuka) - one of the oldest Russian-speaking hacker forums - had been attacked and had its member data leaked.
Since the beginning of the year, other communities in the same business had the same fate. Quezon city west ave zip code. Virtual webcam. The person tipping us about Maza also shared screenshots of posts about attacks on Verified, Dread, and Club2Crd.
On February 15, the Verified administration lost control of the site to unknown operators who had exploited a vulnerability.

A day later, a super-moderator of Club2Crd announced that their account had been hijacked to scam forum members and steal their money.
The same month, Dread was the target of multiple attacks, and the administrator forced new security measures to prevent further disruptions.
Dmitry Volkov, Group-IB CTO, says that card shop breaches are uncommon. With Swarmshop, the assumption is that it was the target of a revenge hack that caused all sellers to lose their goods and personal data.
